WebThe donor uses the pilus to contact the recipient. The pilus then shortens and draws the two bacteria together, at which time the donor bacterium transfers genetic material to the recipient bacterium. WebBacterial conjugation is the transfer of genetic material between bacterial cells by direct cell-to-cell contact or by a bridge-like connection between two cells. [1] This takes place through a pilus. [2] It is a parasexual mode of reproduction in bacteria.
